4.17-stable review patch. If anyone has any objections, please let me know.

From: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>
[ Upstream commit e3f329c600033f011a978a8bc4ddb1e2e94c4f4d ]
The reported residue is already calculated in BURST unit granularity, so
advertise this capability properly to other devices in the system.
